child's daily life, because the goals in bimanual training are more functional. CIMT has some advantages, such as therapists being able to solely focus on the affected arm, and the child having no choice but to use the affected arm in their activities of daily life as their unaffected arm is constrained. In bimanual training, the child may continue to use the unaffected arm to compensate if their therapist or parent does not remind them to use both hands. However, there is only some benefit from therapy. Treatment is usually symptomatic and focuses on helping the person to develop as many motor skills as possible or to learn how to compensate for the lack of them. Nonspeaking people with CP are often successful availing themselves of augmentative and alternative communication (AAC). Therapeutic tests for assessing balance do not appear to have good evidence for their reliability and responsiveness. The tests with the strongest evidence are the Trunk Control Measurement Scale and the Level of Sitting Scale (when measuring the ability to maintain balance), Timed Up and Go test (when measuring the ability to achieve balance), and the Segmental Assessment of Trunk Control (when restoring balance). Assistive technology Assistive technology is commonly used to promote the independence of people with disabilities. Commonly used technologies for people with cerebral palsy can include patient lifts, electric wheelchairs, orthotics, seating systems, mealtime aids (such as large-handled cutlery and slip-resistant mats), mobility aids, standing frames, non-motorised wheelchairs, augmentative and alternative communication and speech-generating devices. Scope has identified 3D printing as an area of promise in being able to print customised orthotics on-demand. Orthotic devices such as ankle-foot orthoses (AFOs) are often prescribed to achieve the following objectives: correct and/or prevent deformity, provide a base of support, facilitate training in skills, and improve the efficiency of gait. The available evidence suggests that orthoses can have positive effects on all temporal and spatial parameters of gait, i.e. velocity, cadence, step length, stride length, single and double support. AFOs have also been found to reduce energy expenditure. Often children with CP require orthoses, such as casts and splints, to correct or prevent joint abnormalities, stabilize joints, prevent unwanted movement, allow desired movement, and prevent permanent muscle shortening. Orthoses may also make it easier to dress or to maintain hygiene. Lower limb splinting is specifically beneficial in providing a base of support and facilitating walking. It is equally important
